' (Cl. 20s- 2) 's claim.

My invention relates to improvements in containers or receptacles for storing or shipping fluids and 4similar substances, 'and the same has for its object to provide a container for receiving and shipping chemica-ls, which is comparatively simple in construction, durable in use, and easy to manufacture.

Eurther, said invention has for its object to provide a container of the character specified which is not subject to the action of the uid or other matter disposed within said receptacle.

Further, said invention has for its object to provide a container forstoring and lshipping of acids, alkalis, and other chemicals or-combinations thereof, and whichl will becapable of resisting the action of said iiuids or substances packed or stored therein.

Further, said invention has for its object to In constructing the container or receptacle III I first form the inner lining consisting v'of'twol heavy layers II, Il* of `gum rubber uponajsuit'-` able foldingor collapsible frame I2, andfthen coverthe outer surface of sai'd layers II, `I Il a thin layer I3 of gum rubber, as shown atv Fi Hereupon the container, as thus far assemb ed.,`

is removed endwise from the frame I2, andE a sheet metaI-shell'or body portion Il, which is v open at its bottom, is slipped over the parts Il, I Il, I3, from the reduced upper endlor neck portion I5 thereof, as shown at Fig. 3. I

Next a bottom frame I2* is inserted into the assembly, andthe bottom lining I9 of acid-proof provide a container of laminated form having an inner wall or lining formed of material which isI Further, said invention has for its object to provide a container in which the several linings orcoatings are so constructed and arranged that the same will not splitl from the metal form or amature as a result of rough handling or ex- Other objects will in part be obvious and in part. be pointed out hereinafter.

To the attainment of the aforesaid objects and ends my invention consists in the novel features of construction, and in the combination, connection and arrangements of parts hereinafter more fully described and then pointed vout in the elevations, partly broken out and in section illustrating the successive steps or operations performed in producing the container. Y

Figs. 2, 3, 4, 5, 6, and 'I are diagrammatic side'- 'rubber disposed against the ends of the frame I2. The edges of the innerv lining II are then turned .inwardly over the bottom lining member I9. and the edges of the lining\member IIn then turned inwardly over the in-turned edges of the lining member II. The circular space between the in-turned edges of the lining member IIl is thereupon filled with a rubber disk I9,

Next. a sheet metal bottom member I6 having a. flange or wall portion I1 extending upwardly and slightly inclined outwardly to correspond to the contour of the open end of the body portion orshell is secured by welding, riveting,`or other convenient means to the body portion or shell Il, as shown atFig. 4. 1

The body portion or shell I l and the bottom member I B are provided with perforations I4n which extend over the entire surface of said body portion and said bottom member.' The body portion Il and bottom member I6 are then provided upon their outer surfaces with a relatively thin layer of -gum rubber I8, corresponding to the layer I3 upon the -inner sides of said body por- -tion and bottom member, as shown at Figs'. 5

and 6. The bottom member I6 is also provided '.upon its inner side with two heavy layers of gum.

rubber I9, I9' corresponding to and merging with the layers II', Il* of the body portion II. When the parts are subjected to pressure and heat the inner and outer layers I3,' I8 will be forced through the apertures Il* of said body portion I4 and bottom member It and cause the layers II, II, I8, and the perforated parts Il, I6, to become bonded into a homogeneous mass. TheV upper ends of the said layers II, IIIl are brought -upwardly out of the container and -carried over the top edge of theperforated shell or bodyporo tion Il, as hereinafter described.

Upon the outer side of the gum rubber layer Il are wound three successive layers of three-A ply cord fabric rubber 2|, 22, 23 'which are an plied inthe form of relatively narrow strips and spirally wound thereon. The angle of the spiral winding being reversed with each successive layer as shown at Fig. 7.

The bottom member Il is provided upon the under or outer side thereof with three layers of cord fabric rubber 24, 2l, 2l which have their edges 24, 25, 28* brought upwards and disposed intermediate the lower separated edges 'of the spirally-wound fabric body layers 2|, 22, 22 and the layer i8. .The upper portions 241, 2l,

24* of said bottom layers 24, 25, 2t become pro' gressively broader or deeper asthe same approach the outer surface of the container, as

shown at Fig. 1.

Beforethe outer layers 22,- 23 are applied n ring 21 of metal or other suitable material is ntted about the neck portion I5 of the container. and retained in position by 'the succeeding layers 22, 23. The body layers 2|, 22, 23 and the bottom layers 24, 25, 28 are then enclosed with s, thin covering oi gum rubber 28, and the whole finally enclosed with a heavy protective coating of rubber 29 having a rim 30 at its base, an intermediate protective band 3l, and an upper,

' annular projection 32 having a recessed lower l. Acontainerofthecharscterdescribedcomprising l! plurality` of relatively thin gum rubber lining members, a metal shell including perforated side and bottom walls interposed between said lining members. and bonded together therewith through the perforations, a plurality of heavier rubber lining members covering the inner side of said lined shell, a plurality of layers of rubber-impregnated fabric each formed ofa relatively narrow band disposed spirally upon said covered shell, yand an outer, heavy covering member of rubber 'enclosing said shell and lining members, all oi' said rubber portions being coalescently bonded together to form an integral unitary structure.

2. vA container of the character described colliprising a plurality of relatively thin gum rubber edge extending around the same and serving as a handle portion for the container. l

The upper end 29* of the coating 29 .is carried laterally inwardly over the upper ends of the thin rubber layer Il, perforated member i4, layer Il, spiral windings 2l, 22 and 23 and the outer thin rubber layer 2l, and the upper ends of the inner heavy layers of rubber Il, Il* are then carried outwardly over the upper end oi the outer coating 28, and thence downwardly over bled as above described, the structure is then subjected to the action of pressure and heat to insure the vulcanization of the whole into s. unitary structure poessingthe required degree of The .cover or closure is formed of metal or other suitable material and comprises a top por- 'tion 4l provided with projecting ears or lugs 42 in which work bolts 43 having their upper ends provided with wing portions 44. 'The bolts 42 engage at their' lower threadedv ends with threaded apertures in the ring 21, and are provided" below saidears or lugs 42 with' washers 4l to limit the upwardmovement of said bolts. 'l'he closure or cover 4I has a depending annular, tapering portion 4l which is .provided with a coating of rubber 41 or other material not Iubiect to the deleterious action of the contents ei the container.- 'nie outer or top surface of the upper end of the outer coating or layer 29 to the ring 21.
